Ah, so it seems that the only way to avoid these 'blending' problems is to leave
the monitor at its native resolution. I understand now. Thanks.
It's worth mentioning that I never saw these kinds of problems on my old CRT
monitors, when adjusting gamma in POV-Ray. (Or, if present, it was subtle, or
else I never noticed.) I'm *guessing* that the reason has to do with the
arrangement of a CRT's red/green/blue phosphors (and its 'shadow mask'),
compared to a modern LCD/LED monitor. If I'm not mistaken, a CRT has something
like a triangular(?) arrangement of phosphors (depending on the brand), whereas
modern monitors have pixels in a strict linear X/Y configuration. I'm thinking
that the gamma chart's thin horizontal lines have a better chance of being
'faithfully' reproduced on a CRT (well, in some sense.) Or so my mind's eye
tells me ;-)

Excellent! That's a subtle bit of re-work magic that most of us would never have
thought of. (OK, maybe just me!)
